Some assume that the problem is tied to the operator or modem. So, AT & T customers have almost no problems, whereas Verizon’s bad.

But there is another problem with Wi-Fi. Some complain that the new iPhone XS and XS Max work better on 2.4 GHz networks than in the 5 GHz band.

I can personally confirm the second problem. My iPhone XS Max works very hard with a 5 GHz wifi. But at the same time, he feels great at 2.4 GHz. And the smartphone often switches to this frequency by itself.
